When people say “nothing can travel faster than the speed of light, information cannot travel faster than the speed of light”
What do we mean by information? and there can be non-information? how it would like?
In: Physics
The speed of light in this case is better called the speed of causality. So for any 2 objects to be causally connected they cant be further apart than over a given time period than light could travel in that given time period. In other words you cant have a cause and effect relationship between objects that haven’t had time to communicate with each other. If you were on the moon and I shined a laser at you, you couldn’t know that I have done so until the light reaches you.
Information can be inferred as anything that can have this causal relationship.
